I have not done agility with my dogs yet... I will be starting this summer. I know they are going to love it because they love learning and more than anything they love to run!!! Especially my trixie, she can run and run all day if she was allowed. I just took her to my dad's today and she ran an hour non stop. I had to calm her down otherwise she would have kept running. She is so fast, sometimes it seems like she's flying. She even extends her whole body so that her stride is faster and longer. The greatest thing is seeing her happy face when she is running, you can tell she was born to run. I can't wait until summer!!
